Hypothesis

Is there a trend towards multiple authorship in occupational medicine journals similar to that in major medical journals?

Conclusion

There is a trend towards multiple authorship in occupational medicine journals, with a direct relationship between higher impact factors and a greater average number of authors per article.

Supporting Evidence

  • The average number of authors per article is increasing in occupational medicine journals.
  • The percentage of single-author articles is decreasing over time.
  • The Journal of Occupational and Environmental Medicine has a significantly higher slope for authorship increase compared to other journals.
  • Occupational Medicine (Oxford) has the highest percentage of single-author articles among the studied journals.
  • Impact factors may influence the trend towards multiple authorship.

Takeaway

More and more people are working together to write articles in occupational medicine journals, just like in other big medical journals.

Methodology

Data was collected from PubMed for publications between 1970 and 2007, analyzing single and multiple authorship in selected occupational medicine journals.

Potential Biases

Potential bias due to the focus on journals with higher impact factors.

Limitations

The study only included six journals and may not represent all occupational medicine journals.

Participant Demographics
